1 Claim.

This invention is particularly of use when drawing beer or other gaseousliquids from barrels or other containers. Generally speaking, the teatand bung holes of a beer cask are closed 5 by means of a cork driventightly into the v crosshead adjustable thereon.

hole and sometimes the hole is tted withA a permanent metal bushing intowhich is driven a wooden or other bung. These corks or bungs aregenerally (when it is desired to draw from the cask) driven into thecask by the rackingV cock or a spile, with consequent damage theretoandato the container, and damage is also caused when the tap is beingremoved. The object of this invention, therefore, is the production ofimproved means whereby the beer or other liquid may be stored and drawnwithout loss ofl gas or Wastage of beer, and no skill or tools areneeded for tapping the barrels or other containers. The tap may beinserted or withdrawn without damaging the ttings or container.

In carrying out the invention a metal bushing is screwed or driven intothe teat or bung hole of the cask. The inner end of the bore of `thisbushing is formed to receive a cork or other bung, while the outer endis tapped to receive a hollow spile or adapter, with which is integrallyformed or to which is screwed or otherwise secured a tap as hereinafterdescribed or of ordinary construction. The spile or adapter is threadedso that it may be screwed into the bushing, and near the end is a numberof ports.

The cork or bung is pushed the required dis* tance into the bushing by asuitable tool and it is removed by the improved spile or adapter whenbeing screwed into the bushing.

A capsule, seal, or other protector may be sprung and/or screwed intothe bushing to prevent the ingress of dirt or other means ofcontamination, the screwed seal being of such a formation as to compressthe cork or bung.

As an alternative arrangement, the cork or bung in the bung hole orbushing may be removed by means of a spile plugged at the inner end witha cork or other plug and having a head temporarily screwed into theouter end to take the blow of the hammer. This head is removed when thespile is in place and an adapter and/or tap, formed with a spile, isscrewed in in its place, the action being such that the cork or bung ispushed from the spile into the container.

The tap which it is preferred to use is one in which the valve is on aslide rod which has a The crosshead carries, and the valve is operatedby, a toggle lever linked to trunnions on the tap body.

In Vorder that the invention may be better understood it will now bemore fully described with the aidof the accompanying drawing, in whichFig, 1 is a sectionalelevation of one part of the invention;

Fig. 2 is a sectional elevation of another part of the invention;

Fig. 3 is a sectional elevation of the parts shown in Figs. 1 and 2assembled;

Fig. 4 is a side elevation of the combination of another part of theinvention with'those parts shown in Figs 1, 2 and l3;

Fig. 5 is an alternative arrangement;

Figs. 6 and 'lare sectional elevations showing alternative arrangementsof the parts shown in Fig. 1;,r v p Figs. 8, 9, 10 and 11 are sectionalelevations of diiierent modications of details, Figs. 8 and 9 being to ascale larger than that of the other figures.

The bushing A is formed with a head AI and a taperedportion A2formedwith an angular `or round thread A3 with a ilat bottom. Aperfectgas-tightjoint is thus obtained when the bushing A is screwed into thehead or bilge-of the cask B. f' Y 'I'he inner end C of the bore of the.bushing A is formed to receive the cork, bung, or other plug CI, whilethe outer end C2 is tapped to receive a spile or adapter and/or tap ashereinafter described. The bore of the inner end C is, as shown in Figs.1, 2, and 8 to 11, of greater diameter than the tapped portion C2. Itmay, as shown in Figs. 6 and 7, be of lesser diameter.

The spile or adapter D is tubular and is threaded at the inner end DI sothat it can be screwed into the bushing A. An undercut shoulder D2 isformed on the spile or adapter D to receive the washer D3 of rubber,cured rubber, or other suitable material. The extreme end D4 is ofreduced outer diameter and is provided with ports D5. A screwed socketD6 or nipple is formed on the outer end to receive a tap. Alternatively,the spile or adapted D may be made integrally with the tap. T'he lengthof the spile D is preferably such that it does not project into thecontainer, thus permitting the latter to be completely drained.Alternatively, it may be of any desired length, such as for use when aspile E (as in Fig. 7) is used in lieu of the bushing A or when thecontainer is placed ing driven but which is removed by the spile DVformed on or secured to a tap F2. The spile D in this case is madelonger than in the case f Figs. 1, 2 and 3.

The tap which it is preferred to use in con-v junction with the parts ashereinbefore described is illustrated in Fig. 4. A valve F on a sliderod FI slidable within the body F2 is adjustably secured to thecrosshead F3. This crosshead F3 carries, and is operated by, a togglelever F4 linked to the trunnions F5 on the tap body F2.V

The lever F4 may be provided with a handle F6 adjustable as to positionthereon. The handle consists of a hand grip F6 and a yoke F1, whichlatter fits over the lever F4 and is tightened against the latter by thescrew F8.

The seat G, made of tinr or other metal, is sprung into a dovetailedrecess GI in the bushing A, as shown in Fig. 8, or over the head Althereof, as shown in Fig. 9. YThis seal is provided for preventing theingress of dirt 4or other foreign matter. The bore may be closed by ascrewed plug H, which may have a conical point Hl as shown in Fig.A 10,whichis forced into and which compresses the cork CI. The point may beformed as a screw H2, as shown in Fig. V1l.

In carrying the invention into effect, metals best suited for theirrespective purposes would be used, and the shape and other details wouldbe varied as found necessary or desirable so long as the essentialfeatures of they invention are retained.

In use, the cask or other container, tted with the bushing A asdescribed and filled as usual, is closed by a cork CI or other bungforced in by a suitable instrument. The seal G is then forced intoposition by a suitable tool or the screw plug I-I screwed in. Then, whenit is desired to draw the contents, the seal is removed by means of asuitable device and the spile or adapter D with tap F2 is screwed intothe bushing, forcing the cork CI or other bung. out at the inner end. lAs the ports D4 are uncovered there is a sudden rush of gas to withinthe spile D and the gas pressure on each side of the cork CI isequalized, with the result that thercork falls away from the entrance tothe spile, as shown in Fig. 3.

A a tap of ordinary construction for attachment to the spile or adapteror formed integrally therewith may be used in lieu of the arrangementshown in Fig, 4.

Having now particularly described and ascertained the nature of my saidinvention and in Vwhat manner the same is to be performed, I

declare that what I claim is:-

Improved means for use in drawing liquids from containers including atubular bushing threaded for engagement with the container, a headintegral with the outer end thereof and provided with a dove-tailedrecess in its outer face, the bore of the bushing being threaded at theend adjacent the head and the remaining inner portion being enlarged andsmooth, a bung in the smooth inner enlarged end of the bore of thebushing and prevented from displacement exteriorly by the threadedportion, a spile engage- Yable with the bushing and including a tubularybody exteriorly-threaded adjacent one end for engagement with theinternal threads 'of the bushing, a shoulder integral with the body Yofthe spile and considerably spaced from the head and provided with anundercut recess, a wide tubular washer on the spile body and clampedbetween the shoulder and the head and Within the recess therein upon theinsertion of the spile body into the bushingl thereby providing aprotective seal against leakage of gas and liquid in addition to causinga displacement of the bung, and an outlet connection on the outer end ofthe spile body.
